HEATING APPARATUS.

Specification of Letters Patent.

Application filed May 7, 1913. Serial No. 766,189.

To all whom t may concern.'

Be it known that l, BAIrrHnLmIY ALBERT Fmivoors GUEsNoN Das MnsNAnDs, citizen of the Republic of France, residing at Latour par Laforce, Dordogne, France, landlord, have invented certain new and useful lmprovements in Heating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to improvements in heating apparatus and particularly that usually termed apparatus for central heating. It is intended to render the working of this apparatus more economical, more regular and safer.

It consists chiefiy in a generator comprising a furnace combined with a boiler in such a manner thatV the steam. produced in the latter, as well as the gases of combustion, are carried away simultaneously to the radiators or their equivalents. It is provided moreover with ejectors and injectors comprising a contrivance for cleaning, that is controlled automatically during the general working of the apparatus.

ln the accompanying drawings which show by way of example a mode of execution of thisinvention7 Figure 1 is a diagrammatic section of a `generator for a heating apparatus of the kind referred to, Fig. 2 is an analogous section on a larger scale of the injector provided in said generator, and Fig. 3 shows a plan of a removable grate with which said generator may preferably be provided.

rlhe generator shown in the drawings comprises: a hopper a, that may be used for storing fuel such as coal, coke or wood, and comprises at its lower portion a cylindrical part al; a frame Z) for holding the hopper a; an annular' plate c mounted on said frame at a certain distance below the lower opening of the cylindrical part a1 and having an inner diameter that is considerably larger than that of said cylindrical part al; a piece al that is generally conical and is provided with an outer rim ZO that rests on the annular plate c, and a series of internal parts d1, parts do and Z1 having between them a number of pipes e arranged in a circle; an annular boiler f tted in the central opening remaining between parts d1 and preferably producing instantaneous evaporation; a grate g, preferably of the oscillating type, arranged beneath the boiler f; a conical piping z, fitted between the boiler ,f and the cylindrical part al of the hopper a, and provided with a series of air inlets surrounded by a casing k1 likewise provided with openings and serving as a damper when operated by means of a rod 71,2; a conical piece z' that serves both as a chamber y' for the gases of combustion (directed downward) and as an ashpit; a supply pipe 7c that branches oii from the receiving chamber' j; and an ejector Z placed at the opening of pipe 7c and connected with the boiler f' in such a manner that it is fed during the general working so as to produce both an aspiration in chamber y' and a forcing action in pipe 7c.

The boiler is connected by a pipe m to a contrivance for supplying air under pres-V sure consisting for instance of a receiver or tank n that is hermctically closed and combined with a small air compressor o that allows of placing the water stored in the receiver under pressure. A throttle device p such a valve or the like is inserted in pipe m. rlhe ejector Z is moreover connected to a device for supplying compressed air according to requirements and consisting for instance of a pipe g placed parallel with pipe m, but branching ofi' from the upper part of the receiver or tank insead of from the lower part of the same. The pipes m and Q are both supplied with cocks m0 and Q0. Pipe 7c is connected up with the usual radiators, that are provided with a suitable exhaust pipe.

The mode of operation is as follows: The ejector Z will .influence the combustion, by drawing air by suction through the apertures of the part L. rlhis air will support the combustion within this part. rlhe suction will also take place within the conduits c, whereby air will be forced against the grate g and the fuel will be burned on the grate. The ejector will furthermore exert a suction' effect at the foot of the discharge pipe 7e leading to the radiators (not shown) and this pipe therefore conveys not only the steam issuing from boiler j' through the ejector, but also the combustion products from the combustion chamber.

ln orderto start the apparatus it is merely necessary to close the cock mo, place some glowing coal on the grate. g, open the cock Q0 and when the combustion has started reverse the position of said cocks, the grate beingv properly supplied With fuel, a large quantity of which can be stored in the hopber a so as to produce an auto-matic Working for a considerable length of time.

The boreV of the ejector Z may,- as shown in Fig. 2, comprise a cylindrical portion Z1 in which apiston Z2 is actuated, the rod of which passes through the opening Vof the bore Without closing the same. sure 'of the fluid will act on the Ypiston so as to regulate the supply of the fluid, and a suitable device can be supplied to produce a reverseV action. This device may consist of a series of annular Weights Z4 that slide freely in the cylinder Z1 and bear against stops Z5,

corresponding parts Z6V arranged at intervals' on rod Z3 being made to: successively abut .againstV the Weights, so as to obtain a continual cleaningzg'Y of the bore. The part k vis 'arranged on the other handso as to be 'l able to slide a little toward thevtop and recrevive asort of fork 1 (Fig. that forms an additional grate for holding back the fuel KAVVVand,V allows of grate g being easily cleaned.

Two cylindrical casings or tubes s, S1 may *0' moreover be arranged between the hopper 3 I bei', the first of these casings vs 'being fast andVV a and plate c, that form anair-tight chamconnected up by a piping so with a chimney v(not shown), through which the air is asi pired 1n case of a stop and througlrwhich the exhaust gases are allowed to escape in an opposite direction. The second casing or tubeslis movable'and can slide upward inY Corales :Hthiny pecentqziay be obtained vfor The presy order to give access to part ZL and the other devices.

The present invention can be applied to any kind of liquid or gaseous fuel by arranging the plant accordingly.

It is expressly to be understood that this mode of execution is only given by way of an example, the devices and arrangements may vary Without departing from the principle of this invention.

The invention may also be applied for using the gases of combustion of any kind of furnace, such as a kitchen stove, the fur- L naces of Works and the like.

Having now described the nature of my invention and the manner in which it is to be performed, what I claim is:
